Super-C® Microstructure
The microstructure of Super-C® is a mixture of high volume hexagonal shaped chromium carbides in a tough austenitic steel matrix. Through a proprietary process, the carbides are perpendicularly aligned to the surface of the clad, making them extremely difficult to dislodge or wear.
Surface Appearance:
All Super-C® plates contain "check relief cracks". These cracks form transversely across the weld bead as the weld deposit cools and occur 3/4" to 2" apart. They are a inherent feature of this product and serve to relieve stresses within the plate. Studies have shown that the stress relief cracks propagate through the clad, but stop when they reach the low carbon steel base plate. The presence of check relief cracks prohibits the use of Super-C® as a structural member. It is intended to be used as liner material for wear protection only.
